Embodiments are disclosed herein that relate to backlighting a display panel comprising color filters via an optical wedge. For example, one disclosed embodiment provides a display panel comprising a plurality of pixels, and also comprising an optical wedge disposed optically upstream of the display panel such that light emerging from the light output interface backlights the display panel. The display system further comprises one or more light sources configured to introduce light into the optical wedge, and a diffraction grating disposed optically between the light sources and the display panel.
